    Error message opening book module in Lightroom

    Exporting JPEG


      I wanna start to create a book in Lightroom 5 but there is an error message (?:0: attempt to call field 'private_PDFL' (a nil value))

      Can anyone tell me what it means? And why I can't access the Book module in my Lightroom. Thanks
